【Abstract】 A sensitive,accurate method is important for early diagnosis of patients with HBV infected,so we established ELISA assay for the detection of PCR amplified sequence of HBV DNA in human serum.Through this method,268 sera from HBV positive or negative patient were detected,the result showed that the ELISA assay based on PCR product is more sensitive and more specific than electrophoresis assay.This method in clinical application was discussed in details in the paper.更多还原
